5 Ways to Recycle Old Concrete | Apartment Therapy

Aug 03, 2011 · Earlier this summer, I wrote about different ways we could remove and repurpose some of the concrete around our home. Since then, we spent one full weekend jack-hammering part of our driveway and random paths around the house. The only problem – we now realize that we have way more concrete rubble than we could possible reuse!Concrete is inherently difficult to dispose of because it’s

Recycling of E-plastic waste as a construction material in

This paper presents an experimental investigation on structural concrete with partial replacement of coarse aggregate using electronic plastic waste (E-plastic). In view of utilizing the non-degradable waste in the construction industry, the E-plastic from computer plastics was considered as coarse aggregate. Coarse aggregate was replaced with different percentages (10, 20, 30, 40 and 50 %) of

Fresh and Hardened Properties of Concrete Incorporating

This paper investigates the use of glass cullet as a 100% sand replacement in Portland cement concrete (glasscrete) systems. Specifically, this paper evaluates the fresh and hardened properties of these systems in comparison with conventional natural sand concretes on the basis of similar 28-day design compressive strength, or the same w/cm.

Effects of Recycled Aggregate on Concrete Mix and Exposure

The unit weight of the concrete ranged from 2365 to 2175 kg/m 3, depending on aggregate content (Figure 6).Increasing the recycled aggregate content reduces the unit weight and density of the concrete, resulting in lighter concrete (Figure 6).The unit weights of the 15%, 20%, and 25% mixes were reduced by 8%, 11%, and 11.5%, respectively, compared to plain concrete.
